I have a YANG ML 25A lathe machine with Fanuc O T series.
Battery went down and it lost all parameters, Parameters have been installed back to the machine but the problem now it cannot read positions for example if I set my zero position (work shift on Z axis) and move Z-40mm, the output or result it only moves -18mm. I changed Parameters from Inches to MM but its still giving me wrong values.

Secondly the feedrate does not change, it uses constant feedrate which does not correspond to the input feedrate value on the program when using G01. It feeds regardless of the feed override turned off to zero.
